Adequate self defense sights have been addressed, but I didn't see anyone post anything about weapons mounted lights. For home defense, these are just as essential as anything else discussed. They help you identify your potential threat as well as temporarily blind them or put them off-balance. Trying to wield a handheld light during an armed encounter with a long gun for self protection can be done with practice, but remember in the middle of the night when you're barely waking up. If nothing is already available, look for a way to attach a short pic rail to the forend and clamp on a TRL or similar.
